Dujiangyan Irrigation System

Dujiangyan Irrigation System is an ancient technological wonder of China. More than 2,000 years ago, Li Bing (c.250-200 BC) served as a local governor of Shu State. At that time, the Mingjiang River flowed fast down from mountains. As it ran across the Chengdu Plain, it frequently flooded the Chengdu agricultural area, and local farmers suffered much from the water disaster. Li Bing and his son designed this water control system and organized thousands of local people to construct the project.
